Build a product waitlist page on Carrd: plan, form setup and launch checks

Pick the plan by where signups should go

Carrd has three form types that can hold a waitlist. Signup forms need Pro Standard and send names and emails to an email service. Contact forms also need Pro Standard and email each submission to up to five addresses. Custom forms need Pro Plus and can send data to email, Zapier, Make, n8n, Airtable, a custom URL or custom JS code. Carrd's plan doc lists forms that accept payments via Stripe Checkout as a Pro Plus feature too. Carrd's custom form doc does not list Google Sheets as a direct destination, so a spreadsheet waitlist would run through one of those automation tools. [1][2][3][10]

Step by step

Provider list and spam options from Carrd's signup form and spam protection docs. Carrd says forms provide baseline spam mitigation even without a provider selected. [1][4]

• Create the list, tag or audience in your email provider and decide whether it uses double opt-in.
• In Carrd, add a Form element, choose the signup type and pick your provider from the supported list (ActiveCampaign, beehiiv, Brevo, Buttondown, EmailOctopus, GetResponse, Ghost, HubSpot, Kit, Klaviyo, Loops, Mailchimp, MailerLite, Mailjet, Omnisend, Resend, Sender, SendFox, SendGrid, Sendy).
• Paste the credentials your provider issues, copied from its dashboard.
• Under the form options, choose a spam protection provider: Cloudflare Turnstile, Google reCAPTCHA v2 or hCaptcha.
• Build a confirmation section that tells people what happens next, and show it after submission.
• Add a one-line privacy note under the form saying what you will send and how to unsubscribe.
• Publish, then run the launch checks below.

Confirmation message and what happens next

Carrd's sections doc says sections can be used for modal-style form confirmations, so a hidden "You are on the list" section is a native way to confirm a signup without leaving the page. [6]

If your provider uses double opt-in, say so in the confirmation: "Check your inbox to confirm." Carrd's forms troubleshooting doc notes that new signups can take a while to appear, especially with double opt-in, and to contact Carrd if nothing appears after 24 hours. For MailerLite, it says you may need to enable double opt-in for API access. [5]

Validation: what to measure before launch

A waitlist exists to answer one question: do enough of the right people want this? Pro Standard includes Carrd's native cookie-free analytics and supports third-party tools such as Plausible, Fathom and Google Analytics, so you can compare visits with signups. [9]

Worked example, hypothetical numbers: you share the page in three communities and it gets 400 visits and 36 signups over two weeks, a 9% signup rate. If one community sent 200 of the visits but only 4 signups, that is where the pitch did not land. Write your go or no-go threshold down before you share the link, so the result is a decision rather than a feeling.

Launch checklist

Carrd's forms troubleshooting doc says Mailchimp errors are usually an incorrect API key or Audience ID, and warns against submitting "test" emails or addresses you previously deleted from the audience. Share images need Pro Lite or higher, and social networks can take up to 24 hours to show a changed image if the link was shared before. [5][7]

Cheaper ways to test the idea first

Carrd's 7-day Pro trial needs no card and includes forms and custom domains, with a 150-element limit, so you can build and test the whole flow before paying. If you want a meta tag such as a search-console verification tag, that is a Pro Standard feature too. [11][8]

You do not need Pro Plus for a waitlist unless signups must land somewhere other than an email service, or you are taking deposits. The jump is $30 a year. [10]
